类似问题中的许多建议似乎都围绕XCode，但是xcode-select --install说命令行工具已经安装。
任何帮助表示赞赏。
我今天遇到了同样的问题，并在深入研究后设法更进一步config.log并检查这篇文章here https://stackoverflow.com/a/63972598/5343630.
我必须采取相反的方向并执行sudo xcode-select --switch /Applications/Xcode.app/从 App Store 下载 Xcode 后。如果你跑clang --version它应该显示Apple clang version 12.0.0 (clang-1200.0.32.27).
我能够执行pyenv install 3.9.0并通过C compiler cannot create executables错误，但不幸的是仍然失败。config.log这次很大，看看我能不能找到什么。
编辑：我通过执行以下命令（包括找到的补丁）成功安装了 3.8.0here https://koji-kanao.medium.com/install-python-3-8-0-via-pyenv-on-bigsur-b4246987a548.

已经有一些 macOS 11.0 合并，但我假设用于pyenv install命令根本还没有更新。不过，这个解决方法目前足以满足我的需求。
